Fuel and R efue lin g
Gasoline additives
A major concern among many auto manufactur
ers is carbon deposit build- up ca used by the type
of gasoline you use.
Although gasoline grades differ from one manu
facturer to another, they have certa in things in
common. All gaso line grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake valves. Al
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP T IER Detergent Gas
oline. For more information on TOP TIER Deter
gent Gasoline, please go to the officia l website
(www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon deposits can rob your en
g ine of peak performance .
CD Note
-Damage or ma lf u nction due to poor fuel
quality is not covered by the Aud i New Vehi

- Do not add aftermarket f uel addit ive prod
ucts to your fuel tank.
Refueling
Fuel filler neck
The fuel f iller neck is located on the r ight rear
side panel behind the fuel f iller flap .
If the power Locking system should fail, you can
still open the flap manually -for deta iled instruc
tions seer:>
page 190 .
You can find the fue l tank capacity of your vehicle
in
c:>page242 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in
formation about fue l specifications, see
c:> page 186 .
Your vehicle fuel tank has an on -board refuelling
vapor recovery system . This feature helps to pre
vent fuel vapors from escaping from the tank and
188
po lluting the environment while you refuel your
vehicle. In order to fi ll the tank properly while
protecting the environment, please follow this
refueling procedure carefu lly.
A WARNING
Under normal operating conditions, never car
ry additional fuel containers in your car. Gas
can isters and other containers used to trans
port fuel can be dangerous. Such containers,
fu ll or empty, may leak and could ca use a fire
in a co llision.
If you must tra nsport f uel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fue l containers . Make cer
tain the container meets industry standards (ANSI/ASTM F852 -86).
CD Note
Never drive your vehicle until the fue l tank is
complete ly empty. The irregular supply of
f u el can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

A discharged battery can freeze at temperatures
of only 32 °F (0 °C). Allow a frozen battery to
thaw comp letely before attempting to charge it
9 & . However, we recommend not using a
thawed batte ry agai n because the batte ry casing
can be cracked due to ice forma tion a nd ca n leak
battery a cid.
Battery charging (Maximum charging rate of
30 amps /14.8 Volt )
When charging at low voltages (e.g. w ith a trickle
c harger ),
the battery cab les do not have to be
d isconnected first. The batte ry caps sho uld
not
be opened when charging a battery.
It is not necess ary to remove the ba tte ry from
t he luggage compa rtment.
Fast charging the battery (charging rate
above 14.8 Volts)
F or technica l reasons do no t use a ba ttery charg
e r that uses voltage grea ter than 14.8 Vol ts to
charge your vehicle's battery .
A WARNING
Charging a battery can be dangerous.
- Always fo llow the operating instructions
provide d by the batte ry charge r manufactur
er when c harging your battery.
Checking and Fillin g
-Never charge a frozen battery. It may ex
plode because of gas trapped in the ice . Al
low a frozen battery to thaw out first.
- Do not reuse batteries wh ich were frozen.
The battery housing may have cracked and
weakened whe n the battery froze.
- Charge the battery in a well ventilated area.
K eep away from open flame or electrical
spark. Do not smoke. Hydrogen gas gene rat
ed by the ba tte ry is explosiv e.
- To reduce the danger of explosion, never
connect or d iscon nect charger cab les wh ile
the charge r is operating.
- Fast cha rging a batte ry is dange rous and
should only be at tempted by a compe tent
technicia n w it h the proper eq uipment.
- Battery acid that may sp ill dur ing cha rging
should be washed
off with a solut io n of
warm water and baking soda to neutralize the a cid .
@ Note
Neve r use a fast charger as a booster to start
the e ng ine . T his w ill ser iously damage sensi
tive elec tronic components, s uch as co ntrol
units , relays, radio, etc. , as we ll as the battery
cha rger.
Battery replacement
The new battery must have the same specifica
tions and dimensions as the original equipmen t
battery.
Intelligent energy management in your vehicle is
r esponsible for distributi ng the elect rical energy
